GSC Track Layouts?

Premium

I noticed some tracks like Goiania, Cordoba, etc, have one layout available to race on, but you can see other layouts when you're racing around, and you could drive along them if you just go through the cones. Does anyone know whether Reiza might make those other layouts available to race on in future updates, or how to do it?

I'd love to take some cars out on those other layouts, not sure how much work would be involved for Reiza to let us use them (being as graphically they are already implemented).
